Flakka is a white or pink crystal synthetic drug that is chemically similar to bath salts. It is usually made from the chemical alpha-PVP, a synthetic version of the stimulant cathinone. Flakka is usually imported from China, Pakistan, and India. The drug is a potent, highly addictive stimulant.
Formic acid, systematically named methanoic acid, is the simplest carboxylic acid, and has the chemical formula HCOOH. It is an important intermediate in chemical synthesis and occurs naturally, most notably in some ants.
Spice is a mix of herbs (shredded plant material) and laboratory-made chemicals with mind-altering effects. It is often called “synthetic marijuana” or “fake weed” because some of the chemicals in it are similar to ones in marijuana. But, its effects are sometimes very different from marijuana, and often much stronger. Usually the chemicals are sprayed onto plant materials to make them look like marijuana.
Because the chemicals used in Spice have a high potential for abuse and no medical benefit, the Drug Enforcement Administration has made many of the active chemicals found in Spice illegal. However, the people who make these products try to avoid these laws by using different chemicals in their mixtures.
Spice is most often labeled “not for human consumption” and disguised as incense. Sellers of the drug try to lead people to believe it is “natural” and therefore harmless, but it is neither. In fact, the actual effects of spice can be unpredictable and, in some cases, severe or cause death.
N,N-Dimethyltryptamine (DMT or N,N-DMT) is a chemical substance that occurs in many plants and animals and which is both a derivative and a structural analog of tryptamine. It is used as a psychedelic drug and prepared by various cultures for ritual purposes as an entheogen.
Boric acid, also called hydrogen borate, boracic acid, and orthoboric acid is a weak, monobasic Lewis acid of boron. However, some of its behaviour towards some chemical reactions suggest it to be tribasic acid in the Brønsted sense as well. Wikipedia
